Almost 40% of the world population and many ecosystems are suffering from water scarcity. Many actions taken in the past have led to the water shortage being experienced today. Evaluate each of the factors listed below. All of these have led to water scarcity EXCEPT: A) sea-level rise B) population growth agricultural demand D) climate change, including drought
Answers
Answer:
Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).
Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.
Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.

Oil spill or a discharge from pipe from a factory or sewage system. Since this is a single point of origin water pollution, this type of water pollution furnish itself to relatively easy remediation.
What is point source water pollution?
Point-source water pollution is the one type of water pollution which is easy to recognize because it generates from a single source or event and affects a specific area.
The negative effects of single point origin is deteriorating water quality which damage the environment, health conditions.
Destruction of biodiversity is another negative effect of water pollution depletes aquatic ecosystems and prompt unbridled proliferation of phytoplankton in lakes called as eutrophication.
The solution to reduce water pollution is reduce carbon dioxide emissions to prevent global warming and acidification of the oceans. Another is to reduce the use of chemical pesticides and nutrients on crops.

Shipping impacts everything from oil and waste in the water to greenhouse gases in the air. But it’s necessary for many aspects of our daily lives. What are some things you can do to help minimize these impacts?
Answers
Answer: Here are some things you can do to help minimize some of these impacts. Don’t smoke inside, Walk or cycle as much as possible to get where you need to go, Keep green plants in the home as they help to clean the air, Choose a cleaner commute, Combine errands and reduce trips. These are some ways to help out. Hope this was helpful!
Explanation:
Gas Exchange and Transport Oxygen and carbon dioxide are exchanged across the walls of alveoli and capillaries. Chemical properties of blood and red blood cells allow for efficient transport of gases throughout the body.Carbon dioxide and oxygen are exchanged across capillary and alveolus walls.Hemoglobin binds with and transports oxygen that diffuses from alveoli to capillaries. It also increases the efficiency of gas exchange.Carbon dioxide is transported in the blood in three ways. Most combines with water and forms carbonic acid. Some dissolves in plasma. Some binds to hemoglobin and proteins in plasma.

a cheetah travels 20km west in an hour. The cheetah stops for another hour. Then the cheetah travels another 40km in two hours. What is the velocity of the cheetah
Answers
Answer:
The velocity of the cheetah is 15km per hour
Explanation:
First, you add the kilometers that the cheetah travels. Then you should get 60km. Then you put the distance the cheetah travels in a ratio to the hours it took for it to reach its point.
60:4
After that you simplify the ratio which should end up with the final ratio being:
15:1
✅The ratio means 15km each hour which is a rate that can be used in velocity. You can convert it further if you needed it to but I hope it helped you!
Explain how the shape and stacking of the thylakoids contributes to the rate of carbon fixation by the chloroplast.
Answers
Chloroplast is the cell organelle that is associated with photosynthesis as it has chlorophyll. When stacked, each thylakoid increases its total surface area, allowing for more electron transport chains to be embedded in each thylakoid membrane.
What is thylakoid?Inside chloroplasts, thylakoids are membrane-bound compartments which are the site of photosynthesis's light-dependent reactions.
Thylakoids are made up of a thylakoid membrane that surrounds a thylakoid lumen. Its main function is to allow the light reactions of photosynthesis.
When the thylakoids are stacked, each of them is able to increase their total surface area which leads to more electron transport chains being embedded into each thylakoid membrane.
Thus, it can be concluded that the shape and stacking of the thylakoids contributes to the rate of carbon fixation by the chloroplast by allowing more electron transport chain.
